A fulgurite is formed when lightning flashes into desert sand and literally melts the sand around the impact site into a glass cast following the shape of the electrical discharge. Obviously, large fulgurites, being thin-walled and elongated as they are, are fragile and hard to obtain. This is a fairly good-sized specimen, though, and from the classic locality for the material that I first was fascinated by as a kid, several decades ago now.
